CURTAIN-ROLLER- SUPPORT.

Application filed December 12, 1921. Serial No; 521,595.

To all whom 2'25 may concern:

Be it known that I. HUGH M. MARSH, a citizen of the United. States, residing at Chicago, Cook County, State of Illinois. have invented certain new anduseful Improve curtain which is paid off of the roller, as where itisdesired to close the window opening. substantially tightly by the curtain whatever amount of curtain is paid off of the roller.

.An important application'of these im provements will be found in connection with ventilating closures for window openings of the general character set forth in the pat ents to Catherine A. Fox No. 1268228 of June 41.. 1918 andNo. 1,249,369 of December A ventilating closure of that general character isalso-illustrated in the accompanying drawings, which. form a part of this specification; and in which Figure 1 is a fragmentary face viewbf window parts.

having the present improvements applied thereto; F 1g. 2 1s a sectional View, on a omewhat enlarged scale, as on the line 22 of Fig, 1.; Fig. 3 is a still more enlarged view, as on the line-8+3 of Fig. 1, showing in full lines the operative position of the roller and its connections, and in dotted lines'the position \of parts when it is desired toreleasethe roller. as ,forremoving thecurtain therefrom as foncleaning it;

Fig. 4 is a view at right angles to the view of Fig. 3 in the direction of the arrow 4 4; F 1g. ,5 is a VlGW ShOWlIlQj the mount ng at the otheriend of the roller, as on the line 5-5- of Fig. 1; and Fig-6 is an end View of the roller with a curtain: thereon showing the locking p wls and the attachment of the curtainto theroller. i

The window sash. comprises. the usual stiles 10 and the horizontal rail- 11, a'nd is in its upward movement.

mounted for up and down movement in the frame comprising the jambs 12 and the sill 13. The mountings or supports for the roller ends include respectively plates 15 and 16 secured as by screws directly upon the sash rail 11. The housing or cover 17, of light sheet metal, is secured as by bolts 18 to the roller supports. The roller and its supports are within this housing, and move with the sashwhen it is raised and lowered.

A plurality of spring clips 20 hold the lower edge of the curtain 21 readily releasably upon the sill 13, and when thejsash is raised the curtain 21 pays off of the roller 22 and covers the window opening, thus providing for ventilation 1 while at the same time excluding'insects, dirt and dust. The

curtain or screen 21 will ordinarily be of fabric having appreciable space between the warp and woof threads for the admission of air.

A material-known as scrim issuitable forthepurpose.

' In order thatthecurtain may effectively a close the window opening for the exclusion of objectionable matter the mountings are so formed that as the curtain pays off of the roller and thetdiameter of the roller and curtainthereon: is decreased, theroller and the curtainthereon will move bodily: toward the desired plane when the curtain isbeing paid off, and in the reverse direction when the curtain is being wound thereon. 1. h

[The plane in whichit is desired to maintain the curtain is defined by'upright rest members 25, which may be. of thin sheet metal, and are shown as angle iron sections secured to the jan bs 12in front of the sash stiles 1.1 and resting substantially against these st-iles the flat-surfacediguides eX- tending at least as high as the roller travels Fmmri s. 2. 3and5 it an is observed 7 that the curtain or screen 21,011 the roller rests against these upright guides or movemeat-limiting bars 25, and it is clear that "so long as the curtain onscreen bn the roller is maintained against fthese'members 25 the curtain will lie. against the members 25 in any voperative position in which the sash may be, thelower end of the curtain being held by the clips 20 sothat thecurtain rests against theseguides 25.

Turning to Fig. 5 we see theright-hand end of. the curtain rollervieWed from in front as in Fig. 1. This end of the'our- -60 the notches 50 are opposite the ends of the hold the projection 4:5 in

tain is provided with theusual axial cylindrical pintle 30. The mounting at that end includes a vertical plate 31 having an upwardly-extending recess 32 and a downwardly and inwardly slanting recess 33, the latter forming a pocket constituting a bearing for the pintle 30. A spring 3%- draws upon a lever 35 pivoted at 36, which lever has an arm overlying the slots 32 and 33. When it is desired to remove or insert the rollerthe'pintle 30' mores the lever out of the way, as shown by dotted lines, permitting the pintle to follow the grooves 33 and 32. The lower end of the recess 33 is formed that the pintle 30 may move toward and away from the upright guide while following the downwardly inclined path provided for it by the groove 33, this downwardly-inclined path insuring that the pull OI'lZGDSiOH upon the "curtain caused by the coiled spring, which is to be understood as being within the, roller'for producing such tension on the curtain, will maintain. the rolled curtain against the guide 25 at'that end or the roller.

Turning to Figs. 2, 3 and 4, the mounting at the left-hand end of the roller, as it would beviewed in Fig. 1, comprises a vertical'plate 40 to which is pivoted at it a swingingarm 42 which is substantially L-sh-aped and to which is pivoted at 43 a second swinging member etl which has a slot adapted to receive and hold the usual rectangular projection 45 issuing trornthat end of the roller and to which projection is secured theicoiled spring S (Fig. 1) within the body of the. roller. and whch it is desired to put under tension for rotating the rollerrelative to the projection 45. The vertical supporting plate 40 has a relatively large middle recess 46 opening toward the guide 25 and when the roller is mounted on the swinging arm 44 the curtain on the roller will be maintained against the guides 25 (by the coiled-spring pressure upon the curtain. As the curtain'pays ofi of the roller that end of the roller will. descend in an arc corresponding with the simultaneous lowering of the pintle 30 (Fig. 5) in the groove 33. j

The roller22 carries the usual pivoted dogs {l7 adapted to engage with notches in a disc connected with: the projection 45 to some temporarilyfixed relative.position, Curtain .rollers of the kind herein referred to are, so well knownfthat it is only necessary to point out here the character of the roller e1 ployed. will be observed from Fig. T6

projection 45 asthere viewed. When the pro ection 45 is in its more horizontal position, as shown inFig. 3, thereis no tendency of a dog/LLto enter a notch 50, since the dog is gravity-controlled; The cur- .tain, may therefore always bepaid off of the roller without interference by the dogs, and, also, so long as the projection 45 is in ts substantially horizontal and operative position, as in Fig. 3, the dog 47 will not catch in a recess 50 when the curtain is wound upon the roller.

In order to lock the pro ection by a 1 41F- oog at provided for changing projection as viewed 4' it will be liniz: i c'ed at one d upon the pi\ ot other end the link i ihas a laterally-pro ecting pin passing through a hole in the end 56 or lever arm 57 (Fig. e) pivoted at 58 upon the supporting plate 59, there being a bell'cranlr extension 60 of this lever having a finger piece 61. From Fig; 3 it will be noted that the pin 55 is below the pivot 43 and this link 54; therefore holds the pivoted end oi the swinging arm 4% against movement when the device is in operation. If, however, thefinger piece 61 is moved in the direction of the arrow (4*4, 3) the connection at 55 will be raised,'as shown by the dotted line positions 01 the link 54 and the pivot 43 will be carried so far away from the guide 25 that the roller and the curtain thereon may swing downwardin front of the guide and the rectangular projection 45 will then assume the substantially vertical position shown by dotted lines in Fig. 3,, one of the notches 50 being then in position to receive the end of one of the pawls or dogs et'I thus locking the projection 45 and maintaining the spring pressure.

With the roller parts so locked it is only necessary to, move the pintle 30, Fig. 5, out or the slots 33 and 32 and then withdraw the roller, the projection 45 easily *oming outof its retainingslot in the swinging arm 44. When it is' desired to replace the roller the linger piece 61. is again moved so as to bring the swinging part 44 into its lowermost position, thereotangular projection 45 is inserted in the slot in the part 441, and the pintle 3() is inserted and moved through the grooves 32 and 33, Fig. 5, and thereupon the curtain is moved bodily upward and the finger piece 61 is released. Thereupon by insert- 'ing' the lower or free end of the curtain (having the usual wood strip 65) beneath the clips 20 the device as a whole is ready tor'use. 1 I The result of this construction is that as the sash is raised and lowered the curtain is -maintained in close association with the curtain-overlapping guides 25, whether only a few turns or many turns of the curtain are paid ofi ot the roller or automatically rewound up'on it, andthe roller with the curtainupon it may be readily removed without means are ction of the From sacrificing the spring-pressure desired for rewinding the curtain.

Means for conveniently securing the curtain upon the roller are shown in F ig. 6 as comprising a longitudinal recess in the roller at 60, the recess having a constricted opening at 61, this recess extending from one end of the roller to the other, and the end edge of the curtain being enlarged as by cording it, that is turning the material over a cord and sewing it, this enlarged edge being inserted in the recess at 60 and being held against retraction when in use by the reduced space between roller parts at 61. The curtain may thus simply be drawn into this recess from one end of the roller where it is held in a manner which does not interfere with the substantially circular winding of the various plies of the curtain.

I contemplate as being within the scope of these improvements various departures from what is specifically herein illustrated and described, as indicated in the appended claims.

I claim:

1. The combination of means defining a window opening, a curtain roller extending thereacross, a curtain wound on said roller,

a mounting at each end of the roller and secured adjacent to the window opening, interengaging means between the roller at each end and the mounting thereat for holding the roller rotatably, each of said mountings being formed to provide a path of movement of the end of the roller thereat toward a predetermined plane in which the curtain is to lie when paid off of the roller,

and means for limiting the movement of the roller toward such predetermined plane whereby the place where the curtain pays ofi of the roller is in such predetermined plane at all stages of the paying off of the curtain from the roller.

2. The combination of means defining a window opening, a curtain roller extending thereacross, a curtain wound on said roller, a mounting at each end of the roller and secured adjacent to the window opening, intercngaging means between the roller at each end and the mounting thereat for holding the roller rotatably, each of said mountings being formed to provide a path of movement of the end of the roller thereat toward a predetermined plane in which. the curtain is to lie when paid ofi of the roller, and stop means against which the curtain on the roll er presses when being paid off of the, roller for limiting the movement of the roller toward such predetermined plane whereby the place where the curtain pays off of the roller is in such predetermined plane at alltimes when the curtain is being paid ofl' of the roller.

3. The combination of means defining a window opening, a curtain roller extending thereacross, a curtain wound onsaid roller, a mounting at each end of the roller and secured adjacent to the window opening, interengaging means between the roller at each end and the mounting thereat for holding the roller for automatic movement in a path toward a predetermined plane when the curtain is drawn upon so as to unwind some thereof from the roller, and iting the movement of the roller toward such predetermined plane whereby the place where the curtain unwinds from the roller is in such predetermined plane at all times when being so unwound therefrom.

4. The combination with a rotatable curtain a roller, of, a curtain wound thereon,

means for holding the ends of the roller for automatic movement toward a vertical plane substantially parallel with the axis of'the roller when the roller is horizontally disposed and when a down-hanging portion of the curtain is means for limpulled upon to unwind the curtain from the roller, and means for limiting the movement of the roller so as tomaintain that part of the curtain which is being unwound from the roller substantially in said plane during the unwinding operation.

5. A mounting for a curtain roller com.- prisinga swinging arm pivotally mounted, said arm having means spaced from the pivotal mounting for engaging a projection at the end of the roller to hold the roller, means for holding the pivotal connection substantially in a given relative position, and means for releasing said pivotal-connection-holding means whereby said swinging arm may move in a direction away position for providing the swinging arm.
